customized EPDM oxygen O-ring products Advantages: good weather resistance and ozone resistance, good water resistance and chemical resistance, can use alcohols and the like, high temperature steam resistance, good impermeability to gas. Cons: Not recommended for food use or exposure to aromatic hydrogen. Seals or parts of sanitary equipment in high temperature water vapor environment. A rubber part in a brake (brake) system. Seals in radiators (car radiators).

　　Compared with other commonly used general-purpose rubber or special rubber, the main performance of customized EPDM oxygen O-ring products lies in the following aspects:

　　1. Customized EPDM oxygen O-ring products are cost-effective, and the raw rubber density is only 0.86-0.90kg/m3. which is a commonly used rubber with light raw rubber density; and it can be filled in large quantities to reduce the cost of rubber materials.

　　2. Excellent aging resistance, weather resistance, ozone resistance, sunlight resistance, heat resistance, water resistance, water vapor resistance, ultraviolet resistance, radiation resistance and other aging properties, and other unsaturated second-type rubbers such as NR, SBR, BR, When NBR and CR are used together, EPDM can act as a polymer or anti-aging agent.

　　3. Customized EPDM oxygen O-ring products Excellent chemical resistance, acid, alkali, detergent, animal and vegetable oil, alcohol, etc.; outstanding water resistance, superheat resistance, water vapor resistance; oil resistance performance.

　　4. Excellent insulation performance, volume resistivity 1016Qcm, breakdown voltage 30-40MV/m, dielectric constant (1kHz, 20℃) 2.27.

　　5. Customized EPDM oxygen O-ring products are suitable for a wide range of temperatures, the lowest operating temperature is -40～-60°C, and they can be used at 130°C for a long time.
